Calendar.CreateControlCollection Method

This method supports the .NET Framework infrastructure and is not intended to be used directly from your code.

Creates a collection to store child controls.

Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)

protected override ControlCollection CreateControlCollection ()
protected ControlCollection CreateControlCollection ()
protected override function CreateControlCollection () : ControlCollection
Not applicable.

Return Value

Always returns an InternalControlCollection.

The CreateControlCollection method is primarily of interest to control developers extending the functionality of the Calendar control.

The following code example demonstrates how to override the CreateControlCollection method in a custom server control so that it always returns a new instance of the EmptyControlCollection class for the Calendar control.
